So the One X comes with a 1.0 Amp charger. The charger would not fit(too long) in the spot where I have been using my Samsung charger.
I compared the two and saw the only difference is the .7 A to 1.0 A. looked up if it was ok to use. Some even reported longer battery life with the slower charger. Makes some sense just lasts longer.
Maybe I am crazy but it seems like I get better battery life from the .7 charger.
I have went back and forth a few times....But of course not enough days to really tell.
thoughts?
Definitely overthinking it. It will just charge slower.

Yep, what he said.
To think of it another way, you can charge your phone via a USB connection to your computer, but it's much slower. This is because USB only provides 0.5 (or maybe it's 0.2?) Amps.
However, going with an adapter that's HIGHER than 1.0A could cause damage.
In the long run, slower charges will likely make your battery last more cycles. But on a per-cycle basis, it should not give better battery life.
If you run your battery down, the smaller charger (and definitely the case for PC USB because they max out at 500ma) may not be able to charge at all. In normal cases, it is fine.
Higher than 1a won't damage anything. .7 might not actually charge the battery 100% depending on if the phone thinks it is usb(500ma charging mode) or ac charger(wont charge properly).

This. The voltage is what really matters. The phone won't draw more than it can to charge. If it draws 1A while charging and you put it on a 2A charger, it will pull 1A. But if the voltages don't match up and there isn't a protection circuit for that type of problem, you could fry the electronics with a higher amperage.
100% on the voltage! That is the important one. .7a shouldnt be recognized as a real ac charger resulting in the phone thinking it is USB 500ma charging mode which is the same as pc, slow. If the device thinks the .7a charger is ac charging mode, the battery probably will never charge to 100%. In fact if you were at 100%, and the phone was in ac charging mode with a .7a charger, it would drain your battery! More than 1a, the phone will only draw what it is capable of. Some aftermarket chargers will still charge in USB 500ma mode because the phone won't recognize them as ac charging 1a mode. I had an old HTC charger once that did funny things to my inspire, it would open navigation every time it was plugged in(thought it was a car dock I guess). Use real OEM chargers if possible. They will charge the fastest, and you won't have issues. The real HTC chargers at 1a are much faster than the aftermarket chargers I have tried. I have a good Kensington 1a car and wall charger, and the HTC blows them away as far as speed!

Actually, AC charging mode or PC USB mode is not determined by amprage or volts (all use 5v). It is determined by how the data pins are terminated. Most non-Apple chargers terminate data pins the same way so they will be recognized as AC charger. Apple chargers are the ones that may not be recognized by the phone as AC chargers because Apple terminates data PINs different than everyone else. Regardless of the charging mode, they all can charge to 100% if they can initiate the charge.
LiIon battery charging circuitary is much more complicated than your normal AA chargers. It is regulated internally so that slightly variations of input voltage won't affect the charging. It has to internally control the charge process precisely so that it can terminate the process at the exact moment (overcharging results in explusion).
Input power supply being 0.7A or 1A has no bearing on the level to which the battery is filled. Even input voltage has no bearing! The only impact to the system will be the rate at which you can charge.
Not true. Some chargers make the device think it is a real ac charger, but do not provide enough to charge to 100%. And yes it has to do with pinout. Some ac chargers aren't recognized properly and results in USB charge mode even if they have more than 500ma available. Even if your pc provides more than the USB standard of 500ma, it will only draw 500ma and charge slowly.
Don't mess with the voltage, it WILL damage your device! The previous post should be ignored, and deleted.

I use my touchpad charger and its 5.3v instead of 5v and its definitely charging my phone faster than the HTC stock charger. No affect on battery life though.
Sent from my HTC One X using XDA
5.3v or 5v is ok because there is a little leeway, and I'm sure the 5.3 isn't exactly 5.3 anyway. If it was, the extra .3v is probably within range, and is not blowing things up, just stressing them a little more, making some heat, and wearing them out slightly quicker.
Try a 12v charger, see what happens. LOL.
Seriously the 5.3v might actually be closer to 5v than a charger labeled 5v and therefore could result in better charging. Remember, input voltage varies as well. Your electricity could go under 100v or as high as 120v. Our electric grid is not very consistent. Supply is constantly being adjusted to meet demand, resulting in widely varying voltages. I have seen it dip into the low 90v range on hot summer afternoons, and rarely in the 115v-120v range where it should be. The 5.0 volt charger would result in the best performance if it was actually putting out a TRUE 5v. A high quality charger, with high quality, consistent, 115v input power that is properly rated is ideal. In reality it doesn't exist.
5.3v close enough, might actually be better. One way to tell, put the voltmeter on it!
If you have access to volt/multimeter, could you post your ac voltage at the outlet and the dc voltage coming out of the 5.3v charger. Could be interesting. How many amps is the charger also? Might have to get one.

Either an input power provides power or it doesn't. The only reason it would "stop" is if the charger in the phone runs out of headroom and I have yet to see this with any AC/DC or USB supply.
The whole issue of whether or not the phone identifies the power supply is an entirely separate discussion. But once it does identify and begin charging it will do so until completion.

This is not true. Take two AC/DC adapters...
A) [email protected] = 4.24W
B) [email protected] =4.00W
The HTC One X has an internal switching charger with dynamic input power limiting. So it will actually be able to draw MORE current from Adapter A than Adapter B. Also, because the charger in the One X is a switching charger there will be negligible extra heat generated and no excessive wear and tear.
how did you know?

Htc has input power limiting? Internal switching charger? Where did you get this information?
The plugpack will be voltage regulated(to protect from overvoltage with under designed load) not ampage regulated.
The battery charges via voltage float, the higher the voltage the quicker the charge, but the voltage is regulated anyways so there is no fast and slow charge. It is charging or it's not. The charge circuit steps up and down the voltage to give fast/slow charge not the plugpack in mobile phones.
1.0a versus 0.7a just means the rated output is lower. It does not change the load. All that happens is the 0.7a will be running over its rated output which results in running hotter and potential running undervoltage.
Running 0.7a is not good if the battery charge circuit will draw 1.0a by design. Your plugpack just becomes a firerisk.
You should always match the designed specifications, eg 12v 1.0a.
The device expects a 12v(or close) input and should be able to draw 1.0a without issue.
If you over or under volt the charge circuit it could blow up, if you over draw the supply it might melt.

Hi,
Wanted your thoughts and opinions on charging speeds. I've never actually timed how long it takes to charge. i leave it overnight and it's ready when i wake up.
When i plug the phone into the charger, it flashes up slow charging for 2 seconds then disappears. which got me wondering how much it's actually using.
i used to use Current Widget app on my Samsung S3 which told me exactly how much current the phone was taking from the charger. typically it was 1A via AC/mains and 499mA from a PC. Plugged in to AC, I could play a power hungry game and it would still charge the phone at a good rate.
The LG kernel doesn't like these apps - the mA value is all over the place but it's typically <500mA displayed.
I could buy a USB ammeter to work out how much the USB charger is supplying but do you have any other methods of finding out? Do you know what your phone uses?
at home, i use a Xtrememac dual USB charger, 2x 2.1A output with a shielded 3M USB cable. for those wondering, it's the same regardless what cable i use. Have also tried with generic usb chargers, iPad chargers and official and OEM cables from LG and various other manufacturers. Have also used a data-shorted USB cable from PC which is the same result.
I haven't tried the LG charger yet (mainly as it's a 2 flat-pin plug and i don't know where i put the box) but i think i recall it being a 1.8A charger.
I use an application called "charger report" which can display current consumption and Xtar "USB detector" device. They both show the same numbers. But Xtar USB detector can detect voltage of a charger. The charging current of LG g pro 2 is 1.4-1.5A when the smartphone is not used and higher when I use it. Using USB detector I found out that this smartphone can charge with maximum current a charger can give only if the charger's voltage is 5.3v. So it chargers at full speed with original charger and two other chargers I have: a charger from my Lenovo s6000 (2A 5.4V) and from my Asus t100 (2A 5.3V).
i tried that app too and got the same results as with Current Widget.
i'll buy a "usb detector". thanks.
I forgot to mention that it take approximately two hours for charging indicator to reach 100% when the smartphone reports that it fully charged. And it's necessary to left it connected to a charger for ten to twenty minutes to be really fully charged. Otherwise charging indicator will soon drop to 90%. One can tell if a smartphone is still charging by touching a charger or by looking at current consumption: a charger would be warm and current would be higher than 200mA.

Hey ray-lee!
I just bought this phone and as it seems it could get someday similar problems as my former phone the Galaxy Note 2.
That phone has had problems with charger and cable also. I had to buy another set of charger and cable since the original ones gave up a few months after i purchased the phone (it was used). The cable managed only 500mA wich is very slow for a battery that strong. One night was once not enough to charge my phone from 30% to 100%. As it seems it is problematic to manufacture cables, that can hold up and continually grant the 1,8 A that would charge our device in just 2 hours. I read somewhere that the G Pro 2 is one of 5 devices that has blazing fast speeds on charging the battery. If you handle the cables with caution hopefully you will not encounter problems. If so my guess is, that you will have a hard time in finding a cable that can hold up. Sadly the stock cables are always more expensive. I do not get it, why companies dont build travel adapters that only charge ur phones built solid with sturdy cables to ensure the transmission of high currents. That way with charger + usb cable is just stupid, even when tis is an all in one solution.
I like this phone very much and i hope, that the cables will not be that sloppy as the cables that Samsung had/ still has. With Current Widget i get readings around 1500 mA (1,5 A) when connected to the stock charger. And yes the LG Charger is an 1,8 A one. I have also flat pins, but received an adapter to be able to connect it in Hugary.
Just sharing thoughts here, that will maybe helpful to someone...

i "think" as long as device has snapdragon it is Quick Charge enabled
I use the "Charging Report" app on my phone, and it reports proper values.
(Around 1500mAh with the LG charger, and around 1600mAh with the 2.0A Samsung charger.)
If your phone is charging slowly, check the CABLE. Cable can broke too.
(Many people complain about their Samsung charging cables, because they just stop delivering power after a while and just charge the device slowly.)

My g flex 2 H959 cant charge while playing games, for example like temple run or even old nokia games like snakes 97?! it will actually drain the battery while charging if i use a SAMSUNG charger and it gains around 1 percent per 5 minutes if i use my LG FAST CHARGING charger, so the question is why lose so much when you play such light games.

turn down the brightness, root your phone and use Greenify and disable or delete bloatware and useless google stuff, force your SD 810 to a lower frequency and so on

It's your usb cable!
The cable quality is very important. Even if you have a good 5V charger, it's useless with a slim and long cable.
The more resistance (ohm) there is on your cable, the more intensity you will lose (A). And the resistance goes by two factor, cable thickness (AWG in USA and mm² elsewhere) and cable lenght. The thinner and the more lenghtful is the cable, the less Amp will go thru.
I have a usb voltmeter and ampmeter so I can give a value on each scenario.
I have a usb charger that can deliver 2.1A and 5V. With a normal cable that was bundled with blackberry (I got them at work) I get 690mA. Cable is 1.2m long and 28AWG is marked on the cable.
With the same charger and a 50cm long cable and 28/22AWG gauge (I suppose it's 28AWG for the data cable and 22AWG for the charging cable), I get 1.29A
With a 3m cable (yes it's long but I have a purpose for it) of unknown gauge, I get 250mA, sometime 300mA maximum. And this intensity it's just a little more than 1W. Even overnight I lose battery percentage.
But with the LG Fast Charger it's all different. It's not labeled Qualcomm Quick Charge 2.0 because it don't deliver 12V. The LG charger deliver 5V and 9V while Qualcomm spec for QC2.0 must be with 12V too. Anyway lets say it's a quick charge 2.0 charger because it act like one.
With the LG charger, with the 3m cable, I have 8.2V and 1.2A which is nearly 10W, more than enough to play and charge at the same time.
I can explain why the 9V tension help with the high resistance of the cable but to make it short it's the same as the big high tension cable in country side, the high voltage help for the long distance even if there is very big cable.
The usb cable provided with the Flex 2 is very good, it's 20AWG on the charging pair. But if you can find shorter cable it's even better (Western Digital cable is very good but to find one of their device bundled with a short and tick WD cable that is not mini usb and not usb 3.0 is very hard).
If you want the fastest charging speed you have to buy a QC2.0 certified charger and a 22AWG or 20AWG short cable. For daily charging I recommand using your old 5V charger (your samsung one).
Thank you so much for this answer bro

What you describe is different from the original post.
First you said that with a 5V charger (samsung) you lose percentage while playing but it was ok with the LG 9V charger.
then you say while answering to me that even with the LG charger you lose percentage but even if your cable is crap, the LG Fast Charger deliver enough power for any situation.
So you really lose percentage while playing with the LG Fast Charger?
And please, no proselytism.

nope but with the lg charger it charges at around 5-8 mins for 1 percents, excuse me but that is wrong , it shouldnt
you meant it's not fast enough or too fast? I don't get your point.
If it's not fast enough, then do not use the phone while it charge or get a Quick Charge 2.0 charger that can do 12V.
If it's too fast, roll back to a 5V charger.
I was always under the impression that it is really bad for the battery to use the phone while it's charging. Perhaps just plug it in and let it charge while not using it is the best solution to charge faster.
I tried a Quick Charge 2.0 charger. The one supplied with our Flex 2 is not a QC 2.0 because it's only 5V and 9V. It still use QC 2.0 spec as at first it's 5V and when it identify the device it deliver 9V but it's not QC 2.0 certified as it don't deliver 12V.
So with a QC 2.0 charger, it deliver 9V too to the Flex 2. That mean that even if the S810 is capable of 12V charging, it's up to manufacturer to specify how it works. It won't charge at 12V.
I don't have another recent snapdragon to test the 12V.
Same!!!
I know its not good for batteries to be used while charging, but for example, i also have a Moto G and its okey playing while its connected to an outlet.
But with my Flex 2 its different, it charges incredibly slow, and worse... it gets HOT! REALLY HOT!
I'm trying now the thermal adjustments suggested by probaina.
Hope it works.
I'm going crazy...
What? My ATT version charges incredibly FAST! Sometimes it gets warm, but nothing I would be concerned about and it's even less after 5.1.1 update. Heck, my M8 gets just as warm if not more.
LMELME83 like OP you have to clarify things, is it slow to charge with a normal 5V charger (like the charger from your old phone) or is it also slow to charge with the charger provided, the LG Fast Charger?
For the 5V charger, the usb cable make all the difference.
For the LG Fast charger or a Qualcomm Quick Charge 2.0 charger, it's all about if the charger recognize your phone and there is no way to tell it on the charger or the phone. You have to use a usb voltmeter. I can recommand one that can take 12V.
Anyway it's normal that the LG G Flex 2 get warmer than the Motorolla Moto G (regardless of the generation because there is 3 or 4 different moto G). Any entry level phone will be colder, like a Core i3 will be colder than a Core i7 even if no one is crazy enough to use a core i7 with the stock heatspread and fan.
Anyome using a 2A charger instead of a turbo charger?
Like a samsung 2A charger
Or a 2A power bank?
Any issues?
Because 1150 mah is too slow
I was also wondering this.I tried it with my 2,4a ipad charger once and it was charging twice as fast, but i dont know if this is good for the phone. Using the normal charger again to be sure.
With normal 1.2A charger, it takes almost 3+ hours for my phone to fully charge. I used my Galaxy Note 10 charger which is 2A and it got charged in 2 hours. I read it in the forums that even with 2A charger, we cant take the advantage of turbo charging as it will need a charger of 2.4A.
I dont know how 0.4A will make a difference but still, my knowledge is limited in this case and wouldnt want to comment on it.
The charger has to be Qualcomm QC 2.0 certified (that's a specification) to take advantage of the turbo charge mode. The amps put out by the charger is kind of secondary in this situation as the charger and phone both need to be "talking on the same page" i.e. QC 2.0
At that point (charger is QC 2.0) the special circuitry kicks in and goes into turbo mode. So its a little more involved than just throwing more amps at the phone. If you google Qualcomm QC 2.0 specification then it will give you a better idea of what it is all about.

Turbo charging steps up to 9v and 12v depending on what wattage the phone can handle.
I think our phones are 15w and the Style is 20w or so.
I can't get my phone to charge faster with a 2amp charger though, only my turbo charger.
I used digitech 2.4amp charge ans works like a charm superb....
It isn't causing any issues? Like battery degradation?

I've been using my Moto turbo charger every night for a couple weeks now and haven't noticed any issues. The phone doesn't seem to let the battery get over 35'C when its charging, so I don't imagine it'll damage the battery.
Think I may get a car charger soon, sometimes I forget to charge at night so it'd be cool to get a full charge on the drive in.
Battery will very likely not last as long when doing fast charging always compared to "normal" charges
Any fact to back that claim?
Im using a Belkin 2.1A charger, no problems whatsoever.
So what's conclusion is it safe to use 2a charger without doing damage to battery

I'm using a 3a charger and it's fine
You can't harm a battery with a higher amperage output charger. The phone will only consume what it is able to. If the voltage was higher (excluding quick charge adapters) then yes that will do damage, but that's a strange situation as no charger should do that unless it's quick charge.
That being said, on hand I do have a feeling that quick charge can actually do long term damage if used a lot but on the other hand, it seems to limit the maximum temperature to around 38'C. Above 40'C can cause irreversible damage to the cell. I'm using a car charger now and when the phone is in use, it gets up to around 38 or 39 and it cuts back on the charging current.
Interesting article explaining Qualcomm, fast charge, turbo charge using all the same technique under different names. They all use the same Qualcomm technique.

Basically, when the charger is unplugged, the adapter runs in 5V mode, which is safe and good. But when the tablet is connected, then it is upgraded to 9V mode. any USB devices connected with a splitter on the charger wire will receive 9V also! This near doubling of voltage could cause devices to be fried, so make sure your Huawei power adapter isn't powering any hubs!!

Good catch!
Thanks for sharing.
I thought charges and/or device ports had a regulator to control input voltage?

Most electronics with a USB port will only be rated for say 5v, or maybe 6v to allow for naughty USB power supplies. 9v is nearly double 5v, and on sensitive low-tech chargers, like resistive ones that charge 18650 or whatever, you could expose the battery to a much higher voltage than what it should have, which could cause an explosion or whatever. I used a fan since it should be able to handle the extra voltage quite happily.
What do you mean fan?
Used a fan to cool what?

There is not problem at all. Qualcomm charge technology and USB 3.1 do the same. The charger and the device negotiate what voltage they want to send the same power but less current (more efficient). You are not supposed to o what you did, it your fault and not from Huawei.

what I was getting at is that if you were to use a splitter, like I did, then be careful, as the voltage might raise. This is not a concern most of the time, but it's good to just be careful.
My OnePlus 5T and it's dash charging only works when these 3 conditions are satisfied:
Dash charger
Stock OnePlus lead
Nothing else plugged in
otherwise it will default down to normal. It's a shame that this didn't happen on the Huawei charger, but hopefully this means that it will be easier for implementation for powerbanks, I can't find any dash charge power banks. And also apparently Huawei phones usually play nice with other chargers. (USB-C power delivery I'm not sure on this device).

I am just annoyed that Huawei do not use QC or USB-PD standards and I must use their charge to charge fast. I do not mind the 9v as my QC devices charges fast on the Huawei charger but not the other way round, forcing me to either change all my chargers or carry an extra charger.
Not sure if you are talking about FCP for in or out of powerbank, I have a Tronsmart powerbank that supports both QC3 and FCP out. It also supports QC in, which means it MAY charge faster with the Huawei's stock charger. I had not tested it that way yet but I think it should as the Huawei charger charges my other QC devices at QC speed.

I know your trouble, I have a OP5t, and that charges at 7.5W from my Huawei charger, when it can charge at 20W using dash charger, my mediapad charges at 10W from the dash charger, out of 18w capability. I do look silly carrying round two chargers with the same plug on them!!
Yeah no dash charger power bank, at least there is a Huawei FCP one like you said, I might get that as my next one, but I've got a lovely EC technologies powerbank, and that only does 10W no matter what, shame really as it is 82whr (massive!).

Luckily (for me at least!), I do not normally carry my M5 around and therefore do not need quick charge on it. Even if taken on holiday, it can charge overnight in the hotel. However this put me off Huawei (and OnePlue, Oppo and any other brands that do not use QC standards) for my future purchase.
Wow, I didn't realize how bad this bites. MediaPad was my first QC3 device. Used it's charger in my bedroom. Then got a LG v35 QC3 phone last week to replace old Nexus 6P (USB C-PD). So excited to see the Huawei charger fast-charging both devices. So irritating to now realize that the LG QC3 charger won't fast charge the M5!
And Huawei is using a proprietary QC3 charging mechanism? ie. are there any compatible chargers on Amazon or only the charger from Huawei will fast charge the M5?

Sorry, Huawei does not use QC standards but their own FCP/SCP instead. QC chargers will not fast charge Huawei gear but Huawei charger MAY charge QC gear fast.
So if I plug my M5 into a standard QC3.0 charger (9v I think), does it at least charge somewhat faster than a standard, non-QC charger? I would assume so. And are they're any 3rd party fasxt chargers compatible w/Huawei's dumbarse proprietary QC3 charging?

No it doesn't, as confirmed by a V/A USB meter. It will only top out at 5V/2A.
I repeat again, Huawei does NOT use QC3 technology, but FCP/SCP technology. If you are looking for a charger that can do both QC and FCP from the same socket, read through the tread again as I had already posted a brand and model that had been tested and confirmed to do both.
Ah, sorry, me dumb and had in my head that M5 was QC3. Now I get it -- FCP, not same as QC3. OK, I see your link and several other chargers compatible w/QC3 and FCP. Thanks!
Hi,
I have a ThinkPad E580 which comes along with a charger Type-C, on the charger has been written : OUTPUT: 20V-3.25A / 15V-3A / 9V-2A / 5V-2A
Is it safe to try charge my MediaPad M5 by this charger?

I had used USB PD adaptors on the M5 before and it charges fine, but not quickly.
My Pad (M5 10.8 WiFi) charges via USB PD with 18 Watts using the 9 Volt Profile. What doesn't work is Quick Charge. Power delivery works fine
Is there anything special about the actual Huawei furnished cable? I need a longer one than what was furnished.

Nothing whatsoever
But get a good one that supports high wattage.
Some cables only transmit 5 watts
Meaning 5v and 1 amp
